As the semanticist Alfred Korzybski often warned, when we split verbally that which is never split existentially we introduce fallacies into our thinking. Korzybski's favorite example was the matter of "space" and "time"; for in experience, we never encounter "space" without "time" or "time" without "space", i.e. a year measures the space the Earth moves around the sun, and the space the Earth travels in one orbit gives us the "time" we call a "year." The verbal seperation of "space" and "time" became such a problem in late 19th Century physics that paradoxes and contradictions multiplied endlessly; and this was only resolved when the genius of Einstein went back before the verbal categories, realized we had created them, and started physics over from the ground up on the simple existential fact that we never encounter "space" or "time" seperately but only the undifferentiated "space-time continuum."
